BlockSlide is the 123rd level in Chip's Challenge Level Pack 2. One of Anders Kaseorg's few levels, it shows his style very well by being different: unlike most ice-on-blocks levels, BlockSlide gives the player the skates, and Chip has to push the blocks as they are sliding on the ice, and coupled with Slide Delay, this leads to a lot of deaths. Fortunately, the level can be completed by cloning four blocks separately as shown by the 715 solution, unlike the similarly difficult Block Buster.
